so i recently had my pc not post after a bios update with the code "Ad" on my Gigabyte AX370-gaming 5 motherboard, but now i just bought a new crosshair VII hero motherboard in hopes this will be the fix. But as i just found out this one launches with EXACTLY the same code....After launching it without RAM i got the 46 code but that seems to be fair afaik. im so lost now and i don't know what i can do to fix this anymore.. i've tried everything, clear CMOS, reseat RAM/GPU, remove all components not needed to boot, multiple monitors / cables, new SSD, no SSD at all, update bios via USB BIOS flashback. PLEASE help me fix this, im really at the end of what i can think off. (could this have something to do with my RAM?)
